[1] Muller was born in Queens, New York and raised on Long Island, the middle child of seven siblings.
Shooting and editing his own stories in most cases, Muller got an immediate and intense education on military coverage as he reported on troop mobilizations from Fort Stewart and Hunter Army Airfield during the raids in Panama and the Persian Gulf War.
After three years in Fort Myers, Muller cracked the "Top 20" market plateau, catching the eye of WFLA-TV, the NBC affiliate in Tampa, Florida.
His big break and return to his hometown in the number-one New York City market came when he got a call from WNBC-TV.
His biggest impact on New York television came when he was chosen to anchor and host a brand-new entry in the local morning news race.
He also served as sports anchor for the broadcast as well as the anchor/reporter/producer of daily business news segments branded "It's Your Money".
